There is also a slight shortage of carbon dioxide, she said, a key element of greenhouse production

Huh?

Industrial greenhouses feed photosynthesis—which is how plants make food by turning carbon dioxide and water into oxygen—a lot more is what I"m assuming this means.

Iceland produces most of their cucumbers in high tech greenhouses using geothermal energy for heat and light.

Greenhouse cucumbers grow best in temps around 25-35c. Since the ambient temp in Iceland is usually cooler than this, venting the greenhouse is uncommon.

As the plants use CO2 in photosynthesis the levels of CO2 in the air decline and the O2 levels increase. The lower levels of CO2 drastically slow down the cucumbers growth. The growers often supplement the plants with CO2 from tanks.
